Other Ubuntu comp is driven by iwl3945 not as mine ath9k. And there is 13 Mb/s same network while 50 strength and I'm having 2-3 Mb/s with 83+ strength. It's rather not interference because I had same low speed while stronger & close channel networks were not broadcasting.

This is why I have mentioned about 2 more comps with 40 Mb/s on same router and channel. Also no difference while closer to router. I can change the channel (tried 4 based on other networks) but this is not applied since still goes on 11 and when I restart the router with channel 4 set, I can not connect at all... Few times spent a while on resetting router back to Auto channel = 11.

Normally I'm ~ 10 meters away. Anyway signal strength seems not to be an issue as gradually closer to router & higher signal did not change the speed.

comment windows 8.1 and ubuntu cant load dual boot option
Beware as wrong BIOS settings are dangerous. You may need to change BIOS settings boot mode from UEFI to LEGACY. The first one will not allow Ubuntu to load. If Your case is one of commons. You enter BIOS by pressing F2 or other key (should be shown for a second or so) after power on.

comment Live USB boot does not work "any more!
This is mad. I'm always booting USB with wingrb installed which allows to have menu and add more options (e.g. .iso) just by copying files and changing the menu file.

And You can not choose the boot device for a single time? Otherwise that could point out if Your USB informs about boot option. On the internet I've found a case related to me a while ago "Access to the BIOS, and change disk support from UEFI to LEGACY , and then your USB-stick will be recognized".

comment Booting only from USB Ubuntu, can I get back to windows 8 on lenovo?
Well BIOS should be accessible. ThinkPad has its' blue button for BIOS settings other than Del or F2. Dunno what Your Lenovo has but I'd lookup that first.

So USB works for other comp but not with the installed & working Ubuntu? And nothing wrong in BIOS? Must be matrix error. Or compatibility of USB's boot sector.

Are You certain You can not change or lookup BIOS settings? For example in my HP 655 I have to press Esc first instead of anything else.

Yeah if BIOS settings are correct then USB drive is not - but then it should NOT work on other comp. Keep in mind that Ubuntu does not affect booting up (that early in boot, it is).

Looks like Your BIOS settings are not set to boot from USB stick (Boot from other devices). Anyway I would try pressing F12 after power on (F12 is common key for Boot menu) and pointing at Your USB drive (must be shown there to be booted). Because Operating system not found. rather says about HDD not the USB.

comment Creating a network with 1 windows pc and 1 laptop using ubuntu 14.04
Hm, I'm a user of NoMachine which helps at remote desktop connections between various Operating Systems. That way You can control Your Win7 from Ubuntu (window or fullscreen) as its' mouse, keyboard and screen would be connected to Win7. I've even managed to do from Internet and send wake up request to Win7 :) . But if You want just to shut the Win7 down there may be less advanced way.
